Narcissus /n?:r's?s?s/ is a genus of mostly spring perennial plants in the Amaryllidaceae (amaryllis) family. Various common names including daffodil,[notes 1] daffadowndilly,[3] narcissus, and jonquil are being used to describe all or some members of the genus. Narcissus has conspicuous flowers with six petal-like tepals surmounted by the cup- or trumpet-shaped corona. The plants are usually white or yellowish (orange or red in garden kinds), with either even or contrasting colored corona and tepals.
Narcissus were well known in early civilisation, both medicinally and botanically, but formally identified by Linnaeus in his Kinds Plantarum (1753). The genus is normally thought to have about ten areas with approximately 50 species. The number of species has varied, depending on how they are categorized, anticipated to similarity between kinds and hybridization. The genus arose some right amount of time in the Late Oligocene to Early Miocene epochs, in the Iberian peninsula and adjacent areas of southwest Europe. The precise source of the name Narcissus is unfamiliar, but it is often linked to a Greek phrase for intoxicated (narcotic) and the misconception of the youngsters of this name who fell in love with his own representation. The English word 'daffodil' is apparently derived from "asphodel", with which it was commonly compared.
The species are indigenous to meadows and woods in southern Europe and North Africa with a middle of variety in the American Mediterranean, particularly the Iberian peninsula. Both cultivated and wild plants have naturalised widely, and were introduced in to the Far East before the tenth century. Narcissi have a tendency to be long-lived bulbs, which propagate by division, but are insect-pollinated also. Known pests, disorders and diseases include viruses, fungi, the larvae of flies, nematodes and mites. Some Narcissus species have become extinct, while some are threatened by increasing tourism and urbanisation.
Historical accounts suggest narcissi have been cultivated from the earliest times, but became increasingly popular in Europe following the 16th century and by the later 19th century were an important commercial crop centred primarily on the Netherlands. Today narcissi are popular as slice blossoms and since ornamental crops in private and open public gardens. The long history of breeding has led to a large number of different cultivars. For horticultural purposes, narcissi are categorized into divisions, covering an array of shapes and colours. Like other members of the family, narcissi create a true number of different alkaloids, which provide some protection for the plant, but may be poisonous if ingested accidentally. This property has been exploited for medicinal utilization in traditional healing and has led to the production of galantamine for the treating Alzheimer's dementia. Long celebrated in fine art and books, narcissi are associated with a true number of themes in various cultures, ranging from death to good fortune, and as symbols of springtime. The daffodil is the national blossom of Wales and the image of malignancy charities in many countries. The appearance of the outdoors flowers in springtime is associated with celebrations in many places.
Narcissus is a genus of perennial herbaceous bulbiferous geophytes, dying back again after flowering with an underground storage light. They regrow in the next yr from brown-skinned ovoid lights with pronounced necks, and reach levels of 5-80 cm depending on species. Dwarf species such as N. asturiensis have a maximum level of 5-8 cm, while Narcissus tazetta may develop as high as 80 cm.
The crops are scapose, having an individual central leafless hollow rose stem (scape). Several blue-green or green, small, strap-shaped leaves happen from the light. The seed stem bears a solitary blossom, but occasionally a cluster of blooms (umbel). The blossoms, that are conspicuous and white or yellowish usually, sometimes both or rarely renewable, contain a perianth of three parts. Closest to the stem (proximal) is a floral tube above the ovary, then an exterior ring composed of six tepals (undifferentiated sepals and petals), and a central disc to conical designed corona. The plants may hang up down (pendent), or be erect. A couple of six pollen bearing stamens surrounding a central style. The ovary is inferior (below the floral parts) consisting of three chambers (trilocular). The berries contains a dried up capsule that splits (dehisces) liberating numerous black seed products.
The bulb sits dormant following the leaves and bloom stem die again and has contractile root base that yank it down further in to the soil. The bloom leaves and stem form in the light bulb, to emerge the next season. Most varieties are dormant from summer season to later winter, flowering in the spring and coil, though a few varieties are fall months flowering.
